The father-and-son owners of a collapsed 19th century East Village antique warehouse will stay out of jail after being sentenced yesterday to $2,000 fines and community service.

Walter Blum, 78, and his son Evan, 49, had faced up to four years in prison after a jury found they endangered the lives of workers and neighbors through shoddy, unauthorized renovations to their property at Houston Street and Second Avenue, which housed Irreplaceable Artifacts.

The landmark four-story building partially collapsed in July 2000.

The father must pay $1,000 in fines, while the son, who Manhattan Supreme Court Justice Gregory Carro said was most culpable as the building site’s supervisor, must pay $1,000 and complete 250 hours of community service.
